BACK-SUPPORTING STANDARD FOR CAR-SEATS.

Application filed August 10, 1915.

To all whom t may concern:

Be it known that I, RICHARD B. MARSH, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State oiPennsylvania, have invented certain new and useful Improvements inBaclrStippo1'ting Standards for Car-Seats, of which the following is aspecification.

My invention relates to standards by which the backs of railwaycar-seats of the walk-over type are supported.

By my invention, standards are made of pressed steel in two pieces whichare formed up and welded together; the outer piece overlies the inner atthe lower portion of the standard, and extends above the inner at theoffset portion formed in both. The oli'set portion of the outer piecehas a projection on each side, `formed over and welded to the offsetportion of the inner piece, to make a box formation at the oiifset ofthe standard,the offset being provided to enable the standard to extendaround the end of the car-seat, which is of a length greater than thatof the back. By this means a very strong construction is provided,combined with light weight. The construction illustrated herewith isalso provided with a pivot-pin integral with or secured to a boxconstruction secured to the lower end of the standard, to enable thepivot-pin to extend some distance beneath the seat, as described in theapplication of Clarence L. Thompson, Serial No. 50,7 22, filed Sept. 15,1915, the box construction being secured to the inner piece or sheet ofthe standard. Rollers adapted to travel on the channel .track of anend-plate, when the back is reversed, are mounted on pins extending intothe standard on the side opposite to the pivot-pin, below an inwardlyextending offset, formed by contacting portions of both sheets orpieces. My invention, however, is not limited in its applicability to acar-seat movement of the character described in the said rThompsonapplication, but in its essential form may be used with any car-seat towhich a steel standard may be adapted.

In order that a clearer understanding of my invention may be had,attention is hereby directed to the accompanying drawings, forming partof this application, and illustrating certain embodiments of myinvention.

In the drawings, Figure 1 is an end ele- Specification of LettersPatent.

vation of a ear-seat and back provided with my improved standard; Fig. 2is an enlarged front elevation of the standard; Fig. 3 1s a verticalsection on line 3-3 of Fig. 2; Figs. l and 5 are transverse sectionstaken respectively on lines 4. l and 5-5 of Fig. 2; and Fig. 6 is asection on line 6-6 of Fig. 3.

Referring to the drawings, the standard represented generally by thereference character 1 is secured to one end oi' the back cushion 2, therollers 3 carried by the standard being mounted on the channel-tracl 4-of the end-plate 5, either the aisle or wall plate, and movablethereover as the back is reversed. The seating angle of the seat 6 isreversed by connection between the stands, one at each end of the backand the rockers 7 by which the seat is supported, such a connectionbeing established, for eX- ample, by the engagement of the pivot-pin 8on each standard within a slot of the lever or connection 9, having aneccentric connec` tion with the rocker, as described, in said Thompsonapplication.

Each standard comprises outer and inner sheets of pressed steel, 10 and11, the sheets respectively being bent outwardly or offset, as shown at12 and 13. The outer sheet 10 terminates a short distance above theoifset portion in a vertical portion 14E, while the inner sheet or pieceextends upwardly a considerable distance, asv shown at 15, to form thearm which is secured to the end of the baclccushion 2. The offsetportion 12, 13, of the standard, is provided to enable the standard topass around the upper edge of the seat 6. Beneath the seat, the sheets10 and 11 may be bent inwardly a slight distance, as shown at 16 and 17,to form a shoulder beneath which the rollers 3 are mounted, the pins onwhich the rollers are mounted extending through the vertical portions 18and 19 of sheets 10 and 11, below the shoulder 16, 17.

The vertical portions of the two sheets below the ol'set 12, 13, andalso below the` shoulder 16, 17, are welded in contact with each other,the vertical upper end portion of sheet 10, above offset 12, alsobeingwelded to the upwardly extending portion 15 of sheet 11. The o'setportion 12 of sheet 10 is 'formed with projections on each side, whichare formed over as shown at 20 and welded to the edges of offset portion18 of sheet 11 to make a 'box formation at` the offset. The pivot-pin 8extends inwardly from the web 21 of the channel or box-formation member22, the inner flanges 23 of which are secured to the portion 19 of sheet11 beneath shoulder 17.

Upwardly extending arm of sheet 1() has its side edges bent inwardly asshown at24, this armpreferablybeing given an Yarched formation,r asshown in Fig. 5, for

'the purpose of strengthening the same. Arm 15 p is f secured by screws,extending through ysorew-lioles in the ari'n 15, into the end oftheseat-cushion. A reinforcing channel member 26 Amay be secured onmember 15, inside fthe edge flanges thereof, to stiffen y'the Y same.

It is obvious that theconstruction de- "scribed strong, light in weightandV ecoiio-ini'calt'omanufact'ureQtheprovision of the vspz'rcedpffsetmembers 12 Aand =13, together "with the sideportions lof offsetvnieniber 12, :welded to member 13, effecting astrong `and rigid boxformation at the offset, `at

which point the greatest strains are encountered theY standard. Itshould lbe understood thatthe standard is applicable for use y with'various types of seats, and that the design and Vproportions oftheoffsetwill vary in accordance with the Construction 'of the seat;

,fHaving now particularly described my invention, what I claim anddesire to proteet by Ije'tters Patent is as follows:

1..In a back-supporting standard, the

combination of a sheet of metal pressed to shape with an upper portionhaving screwho'les therethrough for attachment to a seatback, ahorizontally offset portion, and 4a lower verticalportionbelow theoifset portion, and a second sheet of metal having a Alower verticalportion welded tothe lower vertical portion 'of said first sheet, anolfset portion spaced from the said` first offset portion and a shortvertical portion above 'Contact and offset portions between saidparallel portions, substantially parallel but spaced apart, oneof saidoii'set portions having side portions formed over and welded to fsjaidother offset portion to forni a closed box-'sectiom said offset portionsbeing adapte'dfto permitsaid standard to extend around 'the lend of aprojecting seat-cushion, substantially as set forth.

3. In -a back-supporting standard, the combination of a sheet of nietalpressed to shape -with an upper portion having screwlioles therethroughfor attachment to a seatback, a horizontally offset portion, and a lowervertical portion below the offset portion, and-a second sheet of metalhaving a lower vertical portion welded to the lower vertical portionofvsaid first sheet, an offset portion spaced from the said lirst olfsetpor- "tion anda short vertical portion above said offset portionweldedto the upper -portion of said first sheet, said second offsetportion hai/'ing side projections formed over and welded to said firstoli'set portion, the lower vertical vportions-of said sheets being bentinwardly, adjacent their lower ends, to

forni a shoulder, and thence downwardly in Contact to their lower endsand rollers ymounted beneath said shoulder, substan- Itially as setforth.
